Question

Which of the following is true for a force to come into play?

• A. Two objects must interact.
• B. Two objects need not interact.
• C. Two objects may or may not interact depending on the nature of force.
• D. Can't say.

Answer 1

The correct option is C

Two objects may or may not interact depending on the nature of force.

When a magnet attracts a piece of iron, they need not be in contact. When we have to push an object, we have to get in contact with the object. Thus, it can be said that, for a force to come into play, two objects may or may not be in contact depending on the nature of the force. The two bodies must interact with each other.
